well, did it? because i wanna get an obd1 conversion and i dont wanna buy a S2 manifold. so i was wondering if the 95 gsr had a dual stage so i can just get that year ecu.

 

are you talking about dual stage vtec yes all gsrs have it

 

he's talking about dual stage IM. Not all GS-R's have it! Mine has a single runner IM.
Also, the ECU does NOT activate the second stage of IM, it's activated by pressure so you do not need a new ECU.

the butterflies in the IM are activated by vacuum lines on the B18

 

dont confuse him, though. you are a different generation of GSR.

 

Yes, the GSR has a dual butterfly intake manifold. You shouldnt need a new ECU. Why do you want to convert the intake manifold? Why dont you just get a ITR or Skunk 2?

 

that the whole idea. i dont want to get the s2 or the itr IM. I wanna stick with my dual stage IM and run cams and a full valve train but to get the most out of this set up i need a chipped ecu so i was wondering if i can convert to a 95 ecu with the obd1 conversion. I want to stick with the dual stage manifold. it opens with a vacuum but the ecu spends out a signal or something like that.
